Method for making solid state device utilizing ion implantation techniques

摘要

A method of making a dielectric isolation integrated circuit structure in which dielectric material grooves formed by ion implantation extend down into the structure and intersect a PN junction or other active region at intersection lines such that each intersection line is within microns both laterally from the center of the groove and vertically from the bottom of the groove and the grooves continuously curve at least at the intersection lines at a radius of curvature less than 1 cm.
